Most people I know switch to Reline or RP. I've never changed mine so....

SAE 75W-140 High Performance Rear Axle Lubricant F1TZ-19580-B WSL-M2C192-A
Additive Friction Modifier C8AZ-19B546-A EST-M2C118-A

Need about 3 quarts of the 75-140 and two of the little bottles of mod.

I'm thinking most are. I could be wrong on that, as I don't actually have a Superduty, just the drivetrain, lol.
